Modeling characteristics and process flow of resin sand production line
Resin sand production line is more and more accepted and applied by foundry enterprises because of its clear surface contour, high geometric dimension accuracy, simple and easy production process. With the continuous improvement of the quality requirements of mechanical products, including the improvement of material and dimensional accuracy, especially the surface quality requirements, the advanced technology of resin sand has also been vigorously promoted. In addition, with the treatment of raw sand and the improvement of resin, catalyst, sand mixing equipment and process, the cost of resin sand is reduced and the popularization of resin sand technology is promoted.
Molding characteristics of resin sand production line;
1. High output
The yield of castings is generally ≥ 92, and 96 ~ 98 in higher cases.
2. Smooth surface
It is 2 ~ 3 grades higher than ordinary clay sand, and the surface roughness can reach Ra12 5。
3. High dimensional accuracy
Due to the high strength of molding sand, the dimensional accuracy of castings is two levels higher than that of general tidal molding sand, up to it8-10, which can reduce subsequent machining allowance and reduce tool wear.
4. Resin sand production line is simple and easy to control
Resin sand molding is self hardening, and the key points of the process are guaranteed by equipment. As long as the process parameters are mastered, the casting quality can be guaranteed. Therefore, the requirements for the technical quality of operators are low, which saves labor and reduces labor intensity. The casting output per unit area of the workshop is twice that of clay sand, and the sand cleaning efficiency is greatly improved. At the same time, there are few dust points, less loose sand and clean working environment.
5. High efficiency of resin sand production line
The use of resin sand molding improves the work efficiency, increases the workload per unit area and saves the workshop area.
6. Reduce labor intensity
The resin sand production line greatly reduces the labor intensity of workers in core making, molding, sand dropping, cleaning and other links, which is conducive to the realization of mechanized operation.
